l Specification of'Letters Patent.

Patented April 21, 1968:

Application filed November 21, 1906. Serial No. 344,402.

To all whom it may concern." i ,Be it known that I, JOHN Ross, of thecity and county of Philadelphia, State of Pennsylvania, have invented an1111 rovement in incinerating-Furnaces, of whic the followmg is aspecification.

My invention has reference to incineratin rated character, combined wita lateral incinerating chamber having a perforated floor in rovided withflues for the ame and products of comassage of the and above and throughustion beneath said floor.

My invention further consists in astructure of flues by which theproducts of combustion from the furnace grate shall be di- .vided,- partpassing under the ,incinerating v arch and incinerating floor and-"againbe united abovesaid archand floor before pass ing to the chimney. p

My invention also vco prehends other features, of construction which,together with those above specified, will be better understood by which:

Figure 1 is a longitudinal sectional elevationof an incinerating furnaceembodying .my invention; Fig. 2 is a sectional plan view of the same online 2.2; Fig.- 3 is a transverse sectionof the same on line 3-3; Fig. 4is a perspective view of a portion of one of the narrow arches of theincinerating arch and floor; Fig.5 is a plan view illustrating amodimodification.

fied form of my invention; and 6 is a A is the. furnace grate and B itsbridgewall. C is a flue below the incinerating arch D and iskept atahightem perature by the roducts of combustion from the furnace. herodnets of combustion rise through end ue G and-thence ass backward overthe incinerating arch l and-through -the incinerating chamberI-I to theflue H communicating WiththechimneyJ.

The incineratingarch is. preferably comreference to the drawings in.

'arches E an osed of open work so asto permittheflame om flue to passupwardto the underside of the garbage. onthe arch. and also to on;

able the ashes from the incinerated matter to pass downward into theflue C from which they may be removed through. the side doorsO.

The incinerating arch D consistsofa series of narrow arches E-preferablyof single. bricks properly" shaped and racked. up in arch shape with asmall quantity of fire clay.

as a binder to compensate for uneven faces of l the brick.- I alsoprefer that these arch bricks shall have on one side protuberances S andon the opposite side depressions S as shown in Fig'. 4, so that theparts. S on one brick fit into the recesses S on the adjacent brickthereby making the arch very strong and insured against having1 itsbricks displaced. These narrow arc es E .are preferably about nineinnumber leaving seven.

transverse slotted portions or flues F opening u ward throu h the archand connecting c amber H wit flue C. The end of the arc is provided witha bridge wall D to revent theg arbag'e passing over the end of t e arch.I isan inclined wall which extends obliquely upward from the forward endof the arch arid connects with the flue or throat H leadin to thechimney. The top of the chamber is arched so as to impart more or lessreverberatory action and is furnished with a man hole P ofany suitablecharacter.

. chamber and may be of any width desired; 'it

is located to one side of the incinerating arch D. This chamber isprovided with a'series of narrow arallel arches E constitutin foratedoor. L, said arches being of t e same general character as the arches Eand sepa; rated by open spaces. F. Below this perfoe rated arched floorL is a flueC, Whichcoma per;

municates at one end with the flueC 'adja-I cent to the fire bridge wallB by meansofthe flue I, and at the other" end with the charm. ber Kabove the floor, by flueG. The lines C and C are separated by a w Cwhich-suigorts the ad acent ends of the but said fines are in commu'nication at the end nearest the grate.A and preferably also at thedistant end adjacent to the fluesG and G. If desired the said wall C maybe continued to revent union of the gases, before passing t ough saidfl'uesG q and G..' 4 r The floor L is provided with a bridge. wall 'Lcorresponding to the bridge 1? to-prevent 10 upon the (garbage from fathrough the ening he chamber is provided wit an archedroof which is srung in the direction of the length of the chamberI-I and formstherewith a groined arch structure. roof of the chamber'K is providedwith a V garbage receiving door R of any suitable construction, thatshown consisting of a' circular cast iron frame flanged; at the bottomand which rests a circular-lid or valve. The ably Iprovided with doors Nopposite the fitrch and the chamber K so that rakes may e insertedfordistributin the garbage over 5 the arch. Likewise, the c amber K maybe provided with side doors M to admit rakes or stokers for working thegarbage on the arch L and if desired for transferring it to the arch Dto complete its incineration.

0 The arches E and E are so constructed that they are very strong andbeing independent, may individually expand or contractto difierent derees without affecting the adja-- cent arches. They may bequickly andcheaply repaired and the interlocking. construction of the bricksrenders accuracy in building and stabilityin'use'. It also obviates thenecessity of relying upon cement between the bricks to hold them inlace.

By making the spaces F and between the individual arches E and Econtinuous across the 'incinerating arches D and L there is more s facefor action of the heat frombelow, less ear of clogging by the garbageand fuller opportunity for cleaning in caseofstoppagethan where theapertures are small in area. slots, a through 40 ertures.

The operationofmy. im roved furnace is as follows: The-productsocombustion pass through flues C and C under the .incineratin arches Dand L-thereby heating them; sai.

ea roducts then pass upwardithrough flues G 4 f and travel backabove'the archesl) and L poker or rake may be inserted t in contact withthe garbage upon the arches; the roducts then-pass'into flue H andescape y chimney J. The arbage is dum ed u on the arches D and theoorsand-R respectivelyand is then s read overthe arches. The under partof t e arbage is burned bycontact with theim P 8 is can escent archesand-by the flame upward through the spaces F and F, an the upperportions of the garbage are by the hot gases and reverberato .actionofthe ,roof of the furnace. The as? lowed to pass down through the ap F inthe arches to the fines-C Cbe ow. flame passing through these flues C,C, being very intense, any unconsumed garbage which ma pass down-throughthe apertures F F will be quickly consumed.

The wall C is not actuall required except as a support for the archgs l)and L and it is adjacent ends of these arches will suggest themselves tothe engineer erecting the furnace, should he desire to dispense withsaid wall, Fi 6 being an example.

- It be observed that my-improved furnace has an inciner'ating portionor directly receiving the garba e greatly wider than the flue supplyingthetion, this being to secure a large area for the free flow of theheatin whenlsaturated'with the vapors an ases g The ingases emanatingfrom the garbage.

If desired, anadditional chamber K may "be arranged 'u' on the opposite side of thearch D, and th'is'is indicated at K m Fig. 5. Thiswould still furtherincrease the area of the incineratin part of the furnace and may berendered e ective b "care in supplymg adequate products of cobustion'from the furnace grate A. 1 have shown my I which I'havepreferred to construct it for commercial use, and while I prefer thesamein the form. shown, I do not confine myself to the details, thereof asthey may be modified without departing from the spirlt of my m-.vention. I Having now. described my invention, what I claim as new anddesire to secure by Letters Patent,is:-" In an incinerating furnace, thecombnation of a ate,"a lower flue leading-therefrom throug which theflame passes, an 1ncinerating arch having openings through it arrangedabovetthe, lower flue, an mcmeratingcha'mber'immediatel above themcmerating-arch and connecte with the lower flue at its end most distantfrom the grate, a chimney flue leading from the incineratmg chamberto'the chimney, a lateral incineratin'g chamber opening laterally fromthe mcineratin chamber above the incinerat ng arch an provided with an Iincineratlng arched floor having openings through it, flues for causinghotgases' to pass under and then over the arched floor of the lateral.cham- .ber, and means for charging the furnace with garbalglf.
